Ernest Sosa

For me the two-day workshop was an excellent experience. It was very good to be reminded of all those issues that I had grappled with so intensely in earlier years, and I very much appreciated the opportunity to think about them again and to try to put them in perspective with the stimulus of the critical teams’ focused attention. I am very pleased and grateful for the intense attention and challenge to my views, and for the excellent comments. I will do my best to respond with some helpful discussion.

Ever since Plato it has been thought that one knows only if one's belief hits the mark of truth and does so with adequate justification. The issues debated by Laurence BonJour and Ernest Sosa concern mostly the nature and conditions of such epistemic justification, and its place in our understanding of human knowledge. Presents central issues pertaining to internalism vs. externalism and foundationalism vs. virtue epistemology in the form of a philosophical debate. Introduces students to fundamental questions within epistemology while engaging in contemporary debates. Written by two of today’s foremost epistemologists. Includes an extensive bibliography

Ever since Plato, philosophers have faced one central question: what is the scope and nature of human knowledge? In this volume the distinguished philosopher Ernest Sosa collects essays on this subject written over a period of twenty-five years. All the major topics of contemporary epistemology are covered: the nature of propositional knowledge; externalism versus internalism; foundationalism versus coherentism; and the problem of the criterion. 'Sosa is one of the most prominent and most important epistemologists on the current American scene.' William P. Alston, Syracuse University.

The first paragraph of the article reads: "Classical analysis is concerned neither with cataloguing usage nor with intellectual therapy (except of course by aiming to satisfy curiosity and remove puzzlement). Of recent sorts of analysis, it's the attempt to find the "logical structure of the world" or the "logical form" of various facts that chiefly claims our attention. But philosophers in every period have been absorbed by such analysis. Think of the Greek search for real definitions. Or think of metaphysical appearance/reality distinctions, and attempted reductions of appearance to reality: to monads, to spirits and ideas, or to atomic facts."

In this book, Ernest Sosa explains the nature of knowledge through an approach originated by him years ago, known as virtue epistemology. Here he provides the first comprehensive account of his views on epistemic normativity as a form of performance normativity on two levels. On a first level is found the normativity of the apt performance, whose success manifests the performer's competence. On a higher level is found the normativity of the meta-apt performance, which manifests not necessarily first-order skill or competence but rather the reflective good judgment required for proper risk assessment. Sosa develops this bi-level account in multiple ways, by applying it to issues much disputed in recent epistemology: epistemic agency, how knowledge is normatively related to action, the knowledge norm of assertion, and the Meno problem as to how knowledge exceeds merely true belief. A full chapter is devoted to how experience should be understood if it is to figure in the epistemic competence that must be manifest in the truth of any belief apt enough to constitute knowledge. Another takes up the epistemology of testimony from the performance-theoretic perspective. Two other chapters are dedicated to comparisons with ostensibly rival views, such as classical internalist foundationalism, a knowledge-first view, and attributor contextualism. The book concludes with a defense of the epistemic circularity inherent in meta-aptness and thereby in the full aptness of knowing full well

From the back cover: "Ever since Plato, philosophers have faced one central question: What is the scope and nature of human knowledge? In this volume the distinguished philosopher Ernest Sosa has collected his essays on this subject written over a period of twenty-five years. All the major topics of contemporary epistemology are covered: the nature of propositional knowledge, externalism versus internalism, foundationalism versus coherentism, and the problem of the criterion. The resulting book is a valuable resource for scholars and can serve as a textbook for graduate seminars in epistemology."

There is a controversy in contemporary philosophy over the question whether or not knowledge must have a foundation. On one side are the foundationalists, who do accept the metaphor and find the foundation in sensory experience or the like. The coherentists, on the other side, reject the foundations metaphor and consider our body of knowledge a coherent whole floating free of any foundations. This controversy grew rapidly with the rise of idealism many years ago, and it is prominent today not only in epistemology proper but also in philosophy of science and even in ethics. The discussion of this issue has been lamentably hampered by confusion and misunderstanding, and in this neither side is wholly innocent. The reflections that follow are not meant to settle the controversy, but only to help us understand it more clearly.

In “Tracking, Competence, and Knowledge,” Ernest Sosa notes that in attempting to account for the conditions for knowledge, externalists have proposed that the justification condition be replaced or supplemented by the requirement that a certain modal relation be obtained between a fact and a subject's belief concerning that fact. While assessing attempts to identify such a relation, he focuses on an account labeled “Cartesian‐tracking”, which accounts for the relation in the form of two conditionals. If a person S believes a proposition P → P P → S believes P. Sosa suggests that be abandoned as a requirement, and that, equipped with his modifications, can offer promising results in connection with skepticism. He argues that modified coupled with the requirement that S's belief be “virtuous” can illuminate the nature of propositional knowledge.
